Overview
Retention times of hexane and nonane are 3.5 and 11.6 min respectively (isothermal run at 120 C). Column HP-1, 25m length, .25 mm I.D., 0.33 m film thickness. Carrier gas flow rate is 0.8 ml/min. Calculate the retention time of heptane on the same column at 150 C isothermal, and at the same flow rate. Explain.
